well. inter-operability would be nice for the consumer because he would be able to migrate between one provider to another without investing into a brand new stb which are already sold at a premium. though there are major complications around this concept. first... some providers launched on mpeg2 others on mpeg4. second... antenna position i believe would be different from one player to another depending upon the satellite used? of course. the operators do not want this because all of them suffer. they make most of their money from overpriced STBs. so if they do not get to sell their STBs, they do not make money.
